The Donald David, a Maine Lobster Boat, launched 1956

[SAHaskell]

I am looking for some advice about wiring for led lites in the Donald David. I have encountered a number of LED lite failures that I think are due to me using incorrect sized resistors for LEDs, thus causing too high a voltage for the lights.. I started wiring some lights in series with a single resister but I am now thinking about single resistors for each individual LED except for the three led's in series for the cabin roof lights.
Please advise.

Hi Steve,
Firstly a couple of questions.

What is your battrie voltage?

Do you know the recomended voltage for your LED lights?

Cheers,
Stephen.

I have dozens of LED's wired on my Large Scale railroad. I use a 1000 ohm resistor and 9 to 12 volts DC as a power source.

This is s photo of a simple LD circuit found on the internet.



The battery (DC Input) can vary from 1.5 to 12 volts depending on the size of the resister and brightness of the LED.

If you do a simple Google search for "LED Circuits" you'll find a lot of helpful info.
